Description

一种书籍档案扫描过程的自动对中方法及装置 技术领域
本发明涉及一种装置及方法，具体涉及一种书籍档案扫描过程的自动对中方法及装置。
背景技术
书籍，是指装订成册的图书和文字，在狭义上的理解是带有文字和图像的纸张的集合。在中国原指典籍，图书包括书籍、画册、图片等出版物。书籍是用文字、图画和其他符号，在一定材料上记录各种知识，清楚地表达思想，并且制装成卷册的著作物，为传播各种知识和思想，积累人类文化的重要工具。它随着历史的发展，在书写方式、所使用的材料和装帧形式，以及形态方面，也在不断变化与变更。
随着科技的发展，需要将书籍档案进行扫描来便于阅览和存档，书籍档案在扫描过程中，存在以下问题，1)书籍或者档案的厚度会发生变化，如果不能对中或者对中效果不好会影响扫描影像，照成拍照后产生倾斜；2)扫描组件无法与书籍档案对中时，扫描组件在与书籍档案贴合过程中将造成被扫描件的损害，具体表现在扫描组件在下降时与被扫描件接触，因无法对中，被扫描件将被扫描组件向下摩擦，皱在一起，损坏书籍档案的纸面。
发明内容
本发明所要解决的技术问题是现有书籍档案扫描时没有对中将会影响扫描质量并且对被扫描件造成损坏，提供了一种书籍档案扫描过程的自动对中方法及装置，该装置及方法能够在扫描时实现对中，使得扫描质量得到保证，并且对中后贴合紧密，角度柔和减少摩擦，对书籍档案的纸面进行了保护，保证了书籍档案的安全。
本发明通过下述技术方案实现：
一种书籍档案扫描过程的自动对中装置，包括能够进行竖直方向移动的V形框组件，所述V形框组件下方设置有能够进行横向移动的导向机构，导向机构中设置有用于对横向移动位置进行控制的锁紧机构，在导向机构上方设置有承书机构，并且承书机构能够随着导向机构进行横向移动，V形框组件竖直移动后能够插入到承书机构中。书籍档案扫描是非常重要的工作，尤其是这些需要被扫描的书籍档案都是非常珍贵的，一旦损坏将是巨大的损失，但是现有书籍档案在扫描过程中，书籍或者档案的厚度会发生变化，如果不能对中或者对中效果不好会影响扫描影像，照成拍照后产生倾斜；扫描组件无法与书籍档案对中时，扫描组件在与书籍档案贴合过程中将造成被扫描件的损害，具体表现在扫描组件在下降时与被 扫描件接触，因无法对中，被扫描件将被扫描组件向下摩擦，皱在一起，损坏书籍档案的纸面，对于珍贵的书籍而言，其年代久远，纸面脆弱，很容易被损坏，本方案设计的自动对中装置，能够在扫描时实现自动对中，从而在不会由于影响扫描影像，照成拍照后也不会产生倾斜，并且对中后V形框组件竖直移动后能够插入到承书机构中时，扫描组件在与书籍档案贴合过程中不会造成被扫描件的损害，具体表现在扫描组件在下降时与被扫描件接触，其不会产生向下摩擦，仅仅是贴合，不会皱在一起，书籍档案的纸面得到了保护。
V形框组件包括弯曲的背板以及两个V形框，背板设置在V形框之间且背板的弯曲面分别插入到对应的V形框中，V形框外部设置有龙门架，龙门架上安装有升降系统，且升降系统与V形框连接，V形框在升降系统的作用下进行竖直移动后背板能够插入到承书机构中。背板和两个V形框依次连接形成V型内腔，与书籍展开后形成的页面贴合，使得页面文字或者图案通过透明的背板显现，最后反射到反射镜中扫描出来。
导向机构的上方设置有安装板，安装板设置在导向机构和承书机构之间并且分别与导向机构和承书机构连接，导向机构的下方设置有底板，导向机构安装在底板上，安装板能够在导向机构作用下相对于底板进行横向移动。底板是作为安装导向机构的部件，其与导向机构安装后固定不动，安装板的作为导向机构和承书机构安装的部件，导向机构包括直线导轨，直线导轨安装在底板上，直线导轨的上方设置有若干个滑块，滑块的凹陷部位均与直线导轨的凸出部位扣合，且滑块能够沿着直线滑轨移动，安装板的底部与滑块的顶部连接，锁紧机构设置在滑块之间且能够沿着直线滑轨移动或者扣紧直线滑轨。滑块与安装板固定，这样在滑块移动时就带动安装板移动，整个导向机构分为平行的两组，从而使得稳定性更高，对中更加准确。
为了增加滑块移动时轨迹更加统一，避免造成偏移后出现滑块在直线导轨上卡死，在直线导轨上方设置有直线导杆，且直线导杆与直线导轨平行，直线导杆穿过设置在同一个直线导轨上的滑块和锁紧机构，通过直线导杆穿过该滑块和锁紧机构，从而更加使得移动轨迹更加易控制。
承书机构包括两块沿着铅垂线对称设置的承书板，承书板底部均与安装板顶部固定，承书板之间的角度是可以调整的，其调整是根据书籍档案的厚度不同进行电动调节的。其最后的状态是承书板与待扫描书籍档案贴合，承书板之间形成的角度使V形框的背板与被扫描页面贴合。背板在升降系统的作用下进行竖直移动后能够插入到承书板之间形成的空腔中。
一种书籍档案扫描过程的自动对中方法，包括以下步骤：
(1)将书籍档案放置在承书板上，并将封页固定在承书板上，开启龙门架上的升降系统，将V形框组件从高处逐渐插入到承书板之间形成的空腔中，随着V形框组件下降背板将和被扫描页面逐渐接触，随着V形框组件不断下降，背板与被扫描页面产生挤压力，挤压力将通过承书板传递到安装板上，致使与安装板连接的滑块在直线导轨上移动；
(2)当背板与书籍档案的打开缝隙完全贴合后，安装在承书板上的压力检测传感器给出信号，V形框组件不再下降，同时锁紧机构得到锁紧信号，对直线导轨锁紧制动，安装板将不再相对直线导轨发生直线运动；
(3)扫描完成后V形框组件上升时锁紧机构保持锁紧状态，当书籍档案翻页后，锁紧机构解除制动，V形框组件再次下降，重复上述步骤的运动过程。
本方案通过在V形框组件下降时对被扫描页面产生挤压力，挤压力将通过承书板传递到安装板上，致使与安装板连接的滑块在直线导轨上移动来实现逐渐对中的过程，其完全对中时则根据安装在承书板上的压力检测传感器给出信号，V形框组件不再下降，锁紧机构同步得到锁紧信号，对直线导轨锁紧制动，安装板将不再相对直线导轨发生直线运动并进行扫描，扫描完成后V形框组件上升时锁紧机构依旧保持锁紧状态，直到书籍档案翻页后锁紧机构才解除制动，V形框组件再次下降后锁紧机构再次进行动作，其实现了自动对中，对中精确，将页面能够完全展平，扫描后图像清晰，并且背板和被扫描页面是挤压，无相互摩擦作用，书籍档案的纸面能够得到保护，从而使得珍贵书籍能够长久保存。
本发明与现有技术相比，具有如下的优点和有益效果：该装置及方法能够在扫描时实现对中，使得扫描质量得到保证，并且对中后贴合紧密，角度柔和减少摩擦，对书籍档案的纸面进行了保护，保证了书籍档案的安全。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，下面结合实施例和附图，对本发明作进一步的详细说明，本发明的示意性实施方式及其说明仅用于解释本发明，并不作为对本发明的限定。
实施例：
如图1至图5所示，一种书籍档案扫描过程的自动对中装置，包括能够进行竖直方向移动的V形框组件7，V形框组件7包括弯曲为45°的背板7-1以及两个与背板弯曲角度相同的V形框7-2，背板7-1设置在V形框7-2之间且背板7-1的弯曲面分别插入到对应的V形框7-2中，V形框7-2外部设置有龙门架1，龙门架1上安装有升降系统1-1，且升降系统1-1与V形框7-2连接，V形框7-2在升降系统1-1的作用下进行竖直移动后背板7-1能够插入到承书机构2中，在V形框组件7下方设置有能够进行横向移动的导向机构3，导向机构3的上方设置有安装板4，安装板4设置在导向机构3和承书机构2之间并且分别与导向机构3和承书机构2连接，导向机构3的下方设置有底板5，导向机构3安装在底板5上，而导向机构3包括直线导轨3-3，直线导轨3-3安装在底板5上，直线导轨3-3的上方设置有若干个滑块3-1，滑块3-1的凹陷部位均与直线导轨3-3的凸出部位扣合，且滑块3-1能够沿着直线导轨3-3移动，安装板4的底部与滑块3-1的顶部连接，导向机构3中设置有用于对横向移动位置进行控制的锁紧机构6，锁紧机构6设置在滑块3-1之间且能够沿着直线导轨3-3移动或者扣紧直线导轨3-3，直线导轨3-3上方设置有直线导杆3-2，且直线导杆3-2与直线导轨3-3平行，直线导杆3-2穿过设置在同一个直线导轨3-3上的滑块3-1和锁紧机构6。安装板4下方的导向机构3为两组，每组导向机构3包含有一根直线导轨和数个滑块，根据实际使用选择滑块数量，但是至少要求两个以上，才能使得移动更加顺畅和平稳；直线导轨3-3相互平行且分别安装在底板5上，在每根直线导轨上安装有数量相同的滑块，滑块和安装有承书板的安装板连接在一起，安装板4能够在导向机构3作用下相对于底板5进行横向移动。锁紧机构6优选为电磁锁，电磁锁安装在安装板4的下方，并和直线导轨3-3外形匹配，当电信号给到电磁锁上，电磁锁对直线导轨锁紧制动。
在导向机构3上方设置有承书机构2，承书机构2包括两块沿着铅垂线对称设置的承书板，承书板之间形成V字形角度为45°的部件，承书板底部均与安装板4顶部固定，背板7-1在升降系统1-1的作用下进行竖直移动后能够插入到承书板之间形成的空腔中。被扫描的书籍档案以自然状态打开放在承书板上。背板为一透明的摩擦系数极低的有机材料，安 装在外形呈45°的V形框7-2上，整个V形框7-2能在升降系统的带动下做竖直方向上的直线运动。因为背板的摩擦系数极低，在和被扫描页面接触时，将不会使页面产生褶皱，进而损坏书籍档案。
工作原理及过程：V形框组件作为扫描资料的结构件，在整个自动翻书扫描仪中只能进行竖直方向的直线升降运动，在扫描时，V形框组件的背板应与被扫描页面紧密贴合，才能扫描出最好的效果。在扫描过程中，被扫描页面会不断更换，即在承书板一侧被扫描的书籍档案厚度会由薄变厚，当V形框组件下降过程中，背板将和被扫描页面接触，随着V形框组件不断下降，背板与页面会产生较大的挤压力，挤压力将通过承书板传递到安装板上，致使与安装板连接的滑块在直线导轨上移动，当背板与书籍档案的打开缝隙完全贴合后，压力检测传感器给出信号，V形框组件不再下降，同时电磁锁得到锁紧信号，对直线导轨锁紧制动，安装板将不再相对直线导轨发生直线运动。扫描完成后V形框组件上升时锁紧机构依旧保持锁紧状态，当书籍档案翻页后，锁紧机构才解除制动，V形框组件再次下降时锁紧机构再次进行动作，重复以上运动过程。
通过本方案在扫描时实现自动对中，从而能够使得扫描质量得到保证，并且对中后背板和被扫描页面贴合紧密，不会由于书籍扫描厚度而出现对中状况变化，其设计的角度柔和，能够减少相互之间的摩擦，对书籍档案的纸面进行了保护，保证了书籍档案的安全。
以上所述的具体实施方式，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施方式而已，并不用于限定本发明的保护范围，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。

  4. 根据权利要求3所述的一种书籍档案扫描过程的自动对中装置，其特征在于，所述导向机构(3)包括直线导轨(3-3)，直线导轨(3-3)安装在底板(5)上，直线导轨(3-3)的上方设置有若干个滑块(3-1)，滑块(3-1)的凹陷部位均与直线导轨(3-3)的凸出部位扣合，且滑块(3-1)能够沿着直线导轨(3-3)移动，安装板(4)的底部与滑块(3-1)的顶部连接，锁紧机构(6)设置在滑块(3-1)之间且能够沿着直线导轨(3-3)移动或者扣紧直线导轨(3-3)。
  5. 根据权利要求4所述的一种书籍档案扫描过程的自动对中装置，其特征在于，所述直线导轨(3-3)上方设置有直线导杆(3-2)，且直线导杆(3-2)与直线导轨(3-3)平行，直线导杆(3-2)穿过设置在同一个直线导轨(3-3)上的滑块(3-1)和锁紧机构(6)。
  6. 根据权利要求3所述的一种书籍档案扫描过程的自动对中装置，其特征在于，所述承书机构(2)包括两块沿着铅垂线对称设置的承书板，承书板底部均与安装板(4)顶部固定，背板(7-1)在升降系统(1-1)的作用下进行竖直移动后能够插入到承书板之间形成的空腔中。
  7. 一种书籍档案扫描过程的自动对中方法，其特征在于，包括以下步骤：
    (1)将书籍档案放置在承书板上，并将封页固定在承书板上，开启升降系统(1-1)，将V形框组件(7)从高处逐渐插入到承书板之间形成的空腔中，随着V形框组件下降背板(7-1)将和被扫描页面接触，V形框组件(7)不断下降时，背板(7-1)与被扫描页面产生挤压力，挤压力将通过承书板传递到安装板(4)上，致使与安装板(4)连接的滑块(3-1)在直线导轨(3-3)上移动；
    (2)当背板(7-1)与书籍档案的打开缝隙完全贴合后，压力检测传感器给出信号，V形框组件(7)不再下降，同时锁紧机构(6)得到锁紧信号，对直线导轨(3-3)锁紧制动，安装板(4)将不再相对直线导轨(3-3)发生直线运动，此时进行扫描；
    (3)扫描完成后V形框组件(7)上升时锁紧机构(6)保持锁紧状态，当书籍档案翻页后，锁紧机构(6)解除制动，V形框组件(7)再次下降，重复步骤(1)和(2)的运动过程。
